Notes:
The details of an infrared technique standardized to analyze cotton-polyester blends of different compositions are reported. It is observed that particle size plays a very important role in the peak intensity of the 1725 cm-1 band (C=O stretching) in polyester, the absorption band recommended for analysis of cotton-polyester blends. However, the product of the band width and peak intensity is found to be dependent on particle size to a lesser extent and hence is a more reliable parameter in the measurement of percentage composition. It has further been shown that the method of sample preparation can affect the band width and hence the results. A suitable sample preparation procedure is, therefore, described whereby an accuracy of ±3% in the estimation of polyester content in a given blend can be achieved.
